BACKGROUND Field

The present application relates generally to gloves and moreparticularly to gloves having highly chemical resistant properties.

Description of the Related Art

Many workers wear gloves that provide protection from hazardouschemicals. For example, workers, and especially workers in industrial orlaboratory settings, encounter many types of chemicals, e.g., acids,bases, hydroxides, aliphatic hydrocarbons, aromatic hydrocarbons, and/oraqueous or non-aqueous polar or non-polar solvents and/or solutionscombining any or all of these chemicals, which may further containhydrocarbons or have inorganic chemicals dissolved therein. However, nosingle polymeric barrier can protect against such an array of disparatechemicals and, furthermore, gloves optimized for chemical resistance arethick, inflexible, and often specified for one class of chemicals, e.g.,non-polar hydrocarbons and, therefore, expense is added by having tore-glove often or double-glove when varied in-service applications areencountered. Moreover, workers also want thin, flexible, comfortablegloves for extended use so hands do not tire easily and/or to performdelicate tasks requiring dexterity. The flexibility of a glove is highlycorrelated with the thickness of the glove and increases according tothe inverse of the cube of the thickness. Therefore, a reduction of thethickness of a polymeric glove by 30 percent increases the flexibilityby a factor of three but commensurately decreases chemical resistance.

With the foregoing in view, the inventors herein provide compositepolymeric gloves that are thin, soft, flexible, and highly chemicallyresistant to many classes of chemicals and methods for manufacturing thecomposite gloves.

DETAILED DESCRIPTION

Embodiments according to the invention comprise highly chemicalresistant composite gloves, for example, a composite glove having afirst polymeric layer and a second polymeric layer integrally formedtherewith. At least one embodiment according to the invention comprisesa highly chemical resistant composite glove having an internal(skin-contacting) polychloroprene layer integrally formed with anexternal nitrile layer wherein the composite gloves are thin, soft,flexible, and highly chemically resistant to many classes of chemicals,and methods for manufacturing the composite gloves. The polychloroprenelayer provides softness and flexibility, which is at least one reasonfor having it as an internal layer, as well as chemical resistance for afirst class of chemicals, e.g., organic and inorganic acids, alcohols,alkaline solutions, and oils. A nitrile-butadiene layer providesstrength and chemical resistance to a second class of chemicals, e.g.,weaker acids, such as acetic acid, hydrocarbons, such as heptanes,hexanes, toluene, and xylenes as well as various chemicals such asacetonitrile, acrylamides, carbon tetrachloride, chloroform, and saltsand solutions and blends thereof. Also, an external layer comprising anitrile-butadiene layer can be textured using salts, providing enhancedgrip and durability properties. Additionally, the polychloroprene layermay have a thin coating, for example, made from a low total solidscontent composition, such as a polyurethane, polyacrylic, naturalrubber, synthetic polyisoprene, or nitrile-butadiene material disposedas a thin coating, which is optionally disposed as a skin-contactingcoating and which is soft because of its decreased thickness.Furthermore, the thin coating may offer chemical resistance to a thirdclass of chemicals.

Embodiments of the invention further comprise a third polymeric layer,such as natural rubber or synthetic polyisoprene, disposed on thenitrile layer, producing a three layer glove, i.e.,polychloroprene-nitrile-natural rubber or synthetic polyisoprene, frominterior to exterior. A natural rubber or synthetic polyisoprene layercan provide chemical resistance against a third class of chemicals, suchas, but not limited to, acetone, aldehydes, and some ketones. Also,exemplary embodiments according to the invention comprise a compositeglove in which a polychloroprene layer is sandwiched between a thinnitrile layer (skin-contacting layer) and an external nitrile-butadienelayer.

Embodiments according to the invention further comprise a thin coating,which may be disposed on the two layer gloves or the three layer glovesdescribed herein. The thin coating eases the stripping of the glove(s)from formers, particularly for glove(s) comprising one or more tackypolymers. The coating is stable and robust despite having a long potlife during manufacturing and is therefore inexpensive. The thin coatingcomprises, for example, a nitrile-butadiene composition, a naturalrubber latex composition, or a synthetic polyisoprene composition,having a total solids content of approximately 18-20%. The thin coatingis applied generally by a dipping process as is known to those in theart, which is typically disposed after a leaching step and before acuring step. In at least one exemplary embodiment of the invention, achemical resistant composite glove comprises a thin nitrile-butadienecoating approximately 0.001-0.002″ thick, disposed on a polychloroprenelayer.

The composite glove comprises a thumb 102,an index finger 104, a middle finger 106, a ring finger 108, a littlefinger 110, a palm area 112 and, optionally, a beaded ring 114. Anopening 116 is capable of receiving a hand for donning and doffing thecomposite glove 100. In some embodiments according to the invention,grip features can be disposed into the nitrile layer, as discussedfurther herein.

FIG. 2 depicts a cross section 200 of the composite glove 100 of FIG. 1, according to embodiments of the invention. The cross section 200comprises a first polymeric layer 202, which comprises, for example, apolychloroprene polymeric material. The first polymeric layer 202further comprises an interior surface 204, which is a skin-contactingsurface, i.e., a donning side. The cross section 200 also shows a secondpolymeric layer 206 having an exterior surface 208, which is, forexample, a nitrile-butadiene material and is a highly carboxylatednitrile-butadiene in embodiments according to the invention. Highlycarboxylated, in this context, indicates approximately 30-40%carboxylation or greater. The first polymeric layer 202 and the secondpolymeric layer 206 are integrally formed, meaning that once formedtogether, the first polymeric layer 202 and the second polymeric layer206 cannot be separated without destroying the composite glove 100, andhave little or no gap therebetween. Embodiments of the inventioncomprise wherein the first polymeric layer 202 is thinner than thesecond polymeric layer 206. For example, at least one embodimentcomprises wherein the first polymeric layer 202 comprises a thickness ofapproximately 0.0022″ to 0.0045″ and the second polymeric layer 206comprises a thickness of approximately 0.0036″ to 0.01″.

FIG. 3 depicts an alternative cross section 300 of the composite glove100 of FIG. 1 according to embodiments of the invention. The alternativecross section 300 depicts a third polymeric layer 212, having anexterior surface 214, disposed as an exterior layer on the secondpolymeric layer 206 of the cross section 200, as discussed above.Embodiments according to the invention comprise wherein the thirdpolymeric layer 212 comprises, for example, a natural rubber latex (NRL)or a synthetic polyisoprene material. In at least one embodimentaccording to the invention, the third polymeric layer 212 comprises athickness ranging between 0.003 to 0.01″.

Also, in at least one embodiment according to the invention, thealternative cross section 300 depicts wherein a first polymeric layer202, comprises a thin layer of a polymeric material, for example,wherein the first polymeric layer 202 is approximately 0.001″ to 0.003′thick.

FIG. 4 depicts a flow diagram 400 for methods of manufacturing compositegloves according to embodiments of the invention. The method 400 startsat 402 and proceeds to 404, at which point a former has a coagulantsolution applied thereto, such as by spraying or dipping into acoagulant solution. The coagulant solution may be a solution, forexample, an aqueous or alcoholic solution comprising a concentration of3-12% calcium citrate, calcium nitrate, calcium chloride, acetic acid,formic acid, and/or other salts and/or concentrations as are known tothose in the art. At 406, the coagulant is allowed to dry as coagulantparticles on the former.

At 408, the former having the coagulant applied thereto is dipped into abath of a nitrile material composition, forming a nitrile layer thereon.At 410, the former is dipped into a polychloroprene materialcomposition, disposing a layer of polychloroprene on the nitrilecomposition. The method 400 can then proceed to 412 for finishingtechniques. The finishing techniques 412 comprise, for example, allowingthe first layer, the second layer, and/or the third layer to dry,leaching the first layer, the second layer, and/or the third layer with,for example, water, to remove proteins and impurities, beading the firstlayer, the second layer, and/or the third layer (as discussed below) toform a cuff, curing the first layer, the second layer, and/or the thirdlayer at, for example, 100-135 degrees Celsius for 15 minutes in an ovento form the composite glove.

Alternatively, the method 400, following 410, may proceed to 416, wherea decision is made to dispose a third polymeric layer to form a threelayer composite glove. If the answer is no, the method 400 proceeds to412 as discussed above. If the answer is yes, the method 400 proceeds to418, where the former is dipped into a tank having a natural rubberlatex composition, a synthetic polyisoprene composition, anitrile-butadiene composition, or a blend composition thereof andsubsequently proceeds to 412 for finishing techniques. Embodimentsaccording to the invention may further comprise chlorinating the gloveor adding a coating, such as a polyurethane, polyacrylic, orpolyacrylonitrile-butadiene coating on an exterior surface of the gloveduring manufacturing. It is to be understood that the disposition of athin coating, e.g., a polyurethane coating, a polyacrylic coating, or athin nitrile coating, may be disposed on the composite glove before thecuring process at 412, which aids in stripping. Finally, the compositeglove may be stripped from the former, which inverts the compositeglove.

FIG. 5 depicts an apparatus 500 used to manufacture the composite gloveof FIG. 1 , according to embodiments of the invention. The apparatus 500comprises a controller 502, which controls, for example, production lineequipment, such as electronic circuits for controlling robots thatdeliver glove formers 504 to tanks 510, 520, 530, and an oven 540. Aformer 504 is provided. The former 504 is dipped into a tank 510containing a coagulant 512, such as the aqueous or alcoholic (oraqueous/alcoholic mixture) coagulant as described herein, which becomesdisposed on the former 504 as coagulant particles 514. The former 504 isoptionally heated, for example, pre-heated to approximately 50-70° C.,before dipping into the coagulant tank 510. In either case, pre-heatedor unheated, the former 504 having the coagulant 512 disposed is removedfrom the coagulant tank 510 and allowed to dry. Some embodiments of theinvention comprise removing some of the coagulant using a dipping stepinto water (as discussed further below), which may be used, for example,to limit the amount of polymeric composition (discussed below) disposedon the former 504 in subsequent steps.

The former 504 having the coagulant particles 512 disposed thereon isthen dipped into a tank 520, containing a first polymeric composition522, such as a nitrile material and is removed therefrom. The former 504now has an uncured first composition disposed thereon as a first layer524.

The former 504 is then delivered to a tank 530 containing a secondpolymeric composition 532, such as a polychloroprene material, which isdisposed as an uncured polymeric layer 534 on the uncured firstpolymeric layer 524 discussed above. Optionally, the former 504 isdipped into a water tank, in which the uncured first polymeric layer 524and/or second polymer layer 534 is leached of impurities and/orproteins. The former 504 is then delivered to an oven 540, wherein thefirst polymeric layer 524 and second polymeric layer 534 are cured withheat, as discussed above, to form a composite glove. The curing can beaccomplished in two or more stages of varied temperatures and/or timeperiods, as discussed above. A composite glove 550 (or the compositeglove 100, for example, discussed above) is then stripped from theformer 504, and is optionally inverted, i.e., turned inside out. Asabove, if a third polymeric layer, such as an additionalnitrile-butadiene layer, or, for example, a thin coating, such as a thinnitrile-butadiene coating, a thin natural rubber latex (NRL) coating, athin synthetic polyisoprene coating, a thin polyacrylic coating, or athin polyurethane coating, is added, it may be added before or followingthe curing process.

FIG. 6 depicts a flow diagram 600 for a second method for manufacturingcomposite gloves, according to embodiments of the invention. The method600 starts at 602 and proceeds to 604, at which point a former iswashed, which is optional. At 606, a coagulant is applied on the former,such as by spraying or dipping into a coagulant solution, and is allowedto dry as coagulant particles on the former. At 608, the former havingthe coagulant applied thereto is dipped into a bath of a nitrilematerial composition, forming a nitrile layer thereon. At 610, theformer is dipped into a polychloroprene material composition, disposinga layer of polychloroprene on the nitrile composition.

The method 600 proceeds to 612 for leaching, for example, washing theformer and nitrile/polychloroprene layers in hot water, to removeproteins and impurities therefrom. The method 600 proceeds to a secondleaching operation at 614. At 616, the former having the polychloroprenelayer disposed on the nitrile layer is dipped into a second coagulantbath, for example, a weak coagulant solution. In some embodimentsaccording to the invention, the weak coagulant solution comprises, forexample, an aqueous solution of approximately 2% calcium nitrate. At618, the former is dipped into a polymeric composition having a low TSCfor forming a thin coating, for example, a polyacrylic, a polyurethane,an NRL, a synthetic PI, or a nitrile-butadiene composition, forming athin coating on the polychloroprene layer. The viscosity of the low TSCcompositions are generally lower, for example, between 3-10 cps and aredipped at approximately 28-38° C. Without intending to be bound bytheory, it is believed that the weak coagulant solution allows for athin coating to be disposed on polychloroprene layer. In at least oneembodiment according to the invention, the thin coating is anitrile-butadiene layer that is approximately 0.001″ to 0.003″ inthickness and it at least one embodiment, approximately 0.001″ to0.00225″. The nitrile-butadiene composition may be the same compositionor a different nitrile-butadiene composition than that at 608. In someembodiments, the nitrile-butadiene composition at 618 has a total solidscontent (TSC), for example, 18-20% TSC, that is lower than the nitrilecomposition at 608, for example, generally 30-45% TSC, so that a thinnernitrile-butadiene coating may be disposed on the polychloroprene layer.

The method 600 proceeds to 620, wherein the nitrile and polychloroprenelayers are beaded to form a cuff. At 622, the nitrile andpolychloroprene layers are then cured at, for example, 100-135 degreesCelsius for 15 minutes in an oven to form the composite glove. At 624,the composite glove may be chlorinated. At 626, the composite glove maybe stripped from the former, which inverts the glove and, therefore, thethin nitrile layer becomes a skin-contacting layer. At 628, the method600 ends. It is to be understood that if a salt-texturization process isused to texture, for example, the fingertips, it is typically performedfollowing the curing operation at 622, although it may be accomplishedbefore 622.

Optionally, embodiments according to the invention further comprisetexturization on surfaces of gloves. For example, methods andtechnologies described in U.S. Pat. Nos. 7,771,644 and 8,522,363,wherein salt is impregnated into a tacky layer of nitrile, whichcoagulates the nitrile molecules, and the salt is later dissolved with asolvent to leave multi-faceted cavities/indentations on and within asurface of the nitrile, the entire disclosures of which are commonlyassigned and incorporated by reference in entirety. Also, embodimentsaccording to the invention further comprise an external nitrile layerthat is texturized using a textured former. In some embodiments, thetextured former comprises, for example, a ceramic former having cavitiesdisposed within a surface of the former. The cavities comprise a meanroughness depth of approximately 25-50 micrometers and may be as deep as75 micrometers in depth. Moreover, the former may comprise peaks, whichimpart cavities onto a glove made therewith. In some embodiments, onlythe thumb and/or fingertips and/or palm areas are textured.

Optionally, methods according to embodiments of the invention includewherein the curing of the polymeric layers by heating the non-foamedpolymeric, elastomeric, or latex coating and the foamed coating at afirst temperature and a second curing step at a second temperature,wherein the second temperature is higher than the first temperature.Furthermore, optionally, methods include wherein curing processesinclude heating the first polymeric layer and the second layer ingradients, for example, 50-90° C. for 5-10 minutes and 90-135° C. for 20to 90 minutes.
